NYU Tandon Math Placement Exam

Hello, I have been having trouble trying to figure out what resources to use to study for NYU tandon’s math diagnostic exam. The website only lists topics that could be on the test. When I was prepping for my first attempt, I tried to follow the topics they listed. On the day of the test, everything seemed strangely easy. None of what I studied was on the test, based on the topics listed on the NYU Tandon Math diagnostic test website. It was a 20 question test that seems similar to the College Level Math Accuplacer test provided by College Board. Rather than the topics that were listed on the site. I am very confused as to what to study. My secomd attempt is coming up soon. Any help would be appreciated.
